Use new find-utils in textlint - `linter.lintFile()` use new find-utils

[azu]

Current linter.lintFile() does not ignore absolute file path in any case.
We should change the behavior in next major updates.

Before

.secretlintignore

**/*.md

lint command

$ textlint ./README.md

Results:

...Lint Errrors

After

.secretlintignore

**/*.md

lint command

$ textlint ./README.md

Results: ignore README.md
